Speaking this morning at an annual company media briefing held just before Theresa May gathers her ministers for a crunch summit, he said the government didn't know how to avoid the consequences of Brexit.

He said: "The sun is shining brightly on the UK, the English team is progressing towards the final, the RAF is preparing to celebrate its centenary and Her Majesty's Government still has no clue, no consensus on how to execute Brexit without severe harm."

And he went on to say the situation was "very discomforting" for us - and that they owed it to their shareholders to reveal their fears publicly.

It comes just weeks after the company threatened to pull thousands of British jobs out of the country over our exit.
